Two steps:1) To see how to get your MailChimp action URL (to paste it into the settings), please see the section "How to Setup MailChimp" on this page: http://bilingual-coffee-theme.myshopify.com/pages/theme-features2) One you have the MailChimip action URLs for both the languages you want to use, i.e. one URL for each language, please go to your Theme Settings > Footer and you can paste them into the right text boxes, as attached.
